SELECTING MODES (Discrimination Patterns)
DIGITAL TARGET ID
Target ID can vary widely based upon the target's size
and thickness because small, thin pieces of metal cannot
conduct electrical current as well as thicker pieces of metal.
In addition, mineralized soils can cause Target ID errors,
especially for small targets.
Tip: Target ID is most reliable when the target is centered
under the searchcoil and the coil is swept flat and at a
constant height above the ground.
AUDIO FEATURES
Tone ID—The ACE 200i produces three distinct tones based
on a target’s metal type and conductivity:
• High conductivity targets (Digital ID > 40) produce a
unique belltone signal.
• Medium to low conductivity targets (Digital ID of 21–40),
produce a medium-pitched signal.
• Ferrous targets (Digital ID < 21) produce a low-pitch
signal.
Headphone Jack—Use any headphones with a 1/4” plug.
Example: this is the preset notch discrimination pattern for COINS Mode.
Choose from one of three preset discrimination patterns by
using the MODE button to scroll through the three modes:
• ZERO-DISC Mode–Detects every type of metal. All 5
discrimination pixels are switched on; no metals targets
have been notched out (eliminated). Use this mode to find
all metal items or when the material of the desired object
is unknown. Switch to the Zero-Disc Mode to aid in locating
a target when its signal is inconsistent. Such signals could
mean a trash target is close to a good target.
• JEWELRY Mode–designed to find jewelry such as rings,
bracelets, watches, and necklaces, while ignoring most iron
trash.
• COINS Mode—designed to find most types of coins and
to eliminate common trash items such as iron and foil. Some
desirable items that respond the same as foil may be missed
with this discrimination pattern. Some digging of junk targets
is to be expected, such as aluminum cans.

SENSITIVITY
BENCH TESTS
Use the SENSITIVITY button to step through the four (4)
levels. Use increased sensitivity when searching for very
small or very deep targets. Use lower sensitivity levels when
the detector is behaving erratically (due to excessive metallic
trash, highly mineralized soils, electrical interference or the
presence of other metal detectors) and the erratic operation
cannot be resolved with discrimination.
SENSITIVITY
Button
Sensitivity
Indicator
You should conduct bench tests to become more familiar
with your detector’s operation. To conduct a bench test:
1. Place the searchcoil on a flat, non-metallic surface that is
several feet from other metallic objects.
2. Select the ZERO-DISC mode.
3. Pass various metal objects (coins, bottle caps, nails, etc.)
across the searchcoil at a distance of 8 to 10 cm. Your
metal detector will audibly and visually identify the target.
4. Perform this test in all the modes available on your
detector. Observe the sounds
as well as the graphics on
the LCD that are made in
each mode.
5. Record the results of your
bench tests and refer to them
when hunting in the field.
Once you have determined how your test targets register
on the Target ID during bench tests, test them in the soil. Bury
your targets at recorded depths to create a "test plot." Note
how various targets read based upon whether they are lying
in the ground flat or at various angles.
Keep accurate records or surface markers to indicate your
test plot targets and their depths. Try testing these targets
again in several months after the ground has settled, during
periods of extreme drought or after a soaking rain. Take note
of any changes in how these targets are detected.

HUNTING TIPS WITH YOUR ACE 200i
• If you are new to metal detecting, start searching in areas
with sandy and loose soil to make it easier to learn how to
use your metal detector, pinpoint and dig targets.
• Keep your searchcoil height 2–3cm above and parallel to
the ground at all times for best detection results.
CORRECT
SWING
INCORRECT
SWING
• Swing your searchcoil parallel to plow lines and the
water's edge. This will minimize the negative effects
caused by uneven ground in plowed fields and varying
amounts of moisture near the water. Do not swing the
searchcoil perpendicular to plow lines and the water's edge,
as this may produce abrupt changes in ground response
that can reduce the detector's performance.
• Walk slowly as you scan your searchcoil in a straight line
from side to side at a speed of about 1 meter per second.
Advance the searchcoil about half the length of the
searchcoil at the end of each sweep.
Overlap Swing

1m/sec
1m/sec
In order to fully search an area, overlap the swings of your searchcoil by half
the length of the coil (about 11cm). Sweep the searchcoil in a straight line
or with a slight arc at a sweep speed of about 1m/sec.

specific targets
Target ID Cursor
bounces
1. Ensure batteries are installed in the correct orientation.
2. Replace all old batteries with all new batteries.
1. Ensure your searchcoil is securely connected and the coil
cable is snugly wound around the stem.
2. If using the detector indoors, be aware that excessive
amounts of electrical interference exists, plus excessive
amounts of metal can be found in floors and walls.
3. Determine if you are close to other metal detectors or other
metal structures such as electrical power lines, wire fences,
benches, etc.
4. Reduce your sensitivity setting.
Intermittent signals typically mean you’ve found a deeply
buried target or one that is positioned at a difficult angle for
your detector to read. Scan from different directions to help
define the signal. In the case of multiple targets, switch to
the ZERO-DISC Mode to locate all targets. In trashy areas, use
the Super Sniper™ or a 5" x 8" DD searchcoil. NOTE: Iron
targets may cause Intermittent Signals. You can identify iron
targets in the ZERO-DISC Mode.
Ensure you are using the correct mode for the type hunting
you are doing. If specifically hunting for coins, COINS mode
should be your best choice to eliminate other undesirable
targets. You may also use the ZERO-DISC mode, which
detects all metal targets to ensure desired targets are present.
If your Target ID Cursor bounces erratically, chances are
you’ve found a trash target. However, a Target ID Cursor may
bounce if a good target (such as a coin) is not parallel to the
searchcoil (e.g. on edge). It may also bounce if there is one
or multiple “junk” targets laying next to the good target. Scan
from different directions until your Target ID Cursor becomes
more stable.
NOTE: Large, flat pieces of iron—depending on their
orientation in the ground—can read as a good target or can
cause erratic Target ID Cursor movement.
BATTERY REPLACEMENT
Low Battery
Indicator
The Low Battery Indicator will switch on when the detector's
batteries become weak. The detector will maintain full
performance but the batteries should be replaced soon when
this indicator appears. NiMH rechargeable batteries may be
used, but may have a shorter life per charge. You can expect
20 to 40 hours of operation depending on battery type and
quality.
Replace the batteries by sliding the cover off the control
housing. Remove batteries when the ACE 200i will be stored
for longer than 30 days.
Note: 1.5V/cell Lithium batteries can also be used, but the
use of 3.7V/cell Lithium batteries will damage the detector.

METAL DETECTING CODE OF ETHICS
CAUTIONS
The following is a Code of Ethics that many treasure hunters
and clubs follow to preserve our exciting sport of metal
detecting. We encourage you to do the same:
• I will respect private and public property, all historical and
archaeological sites and will do no metal detecting on
these lands without proper permission.
• I will keep informed on and obey all local and national
legislation relating to the discovery and reporting of found
treasures.
• I will aid law enforcement officials whenever possible.
• I will cause no willful damage to property of any kind,
including fences, signs and buildings.
• I will always fill the holes I dig.
• I will not destroy property, buildings or the remains of
deserted structures.
• I will not leave litter or other discarded junk items lying
around.
• I will carry all rubbish and dug targets with me when I leave
each search area.
• I will observe the Golden Rule, using good outdoor manners
and conducting myself at all times in a manner which will
add to the stature and public image of all people engaged
in the field of metal detection.
When searching for treasure with your Garrett detector, observe
these precautions:
• Never trespass or hunt on private property without permission.
• National and state parks / monuments and military zones, etc.
are absolutely off-limits.
• Avoid areas where pipelines or electric lines may be buried. If
found, do not disturb and notify proper authorities.
• Use reasonable caution in digging any target, particularly if you
are uncertain of the conditions.
• If you are unsure about using your metal detector in any area,
always seek permission from the proper authorities.
CARING FOR YOUR ACE 200i DETECTOR
Your Garrett detector is rugged, designed for outdoor use. However,
as with all electronic equipment, there are some simple ways you
can care for your detector to maintain its high performance.
• Avoid extreme temperatures as much as possible, such as storing
the detector in an automobile trunk during the summer or
outdoors in sub-freezing weather.
• Keep your detector clean. Disassemble the stem and wipe it,
the control housing, and the searchcoil with a damp cloth when
necessary.
• Remember that your searchcoil is submersible, but your
control housing and connectors are not.
• Protect your control housing from heavy mist, rain and blowing
surf.
• When storing for longer than one month, remove the batteries
from the detector.
• When changing batteries, use quality alkaline or rechargeable
batteries, and replace with all new batteries for optimum
performance.
